New Molecule Offers Hope for Chronic Pain Sufferers
A novel molecule shows promise as a long-lasting, targeted anesthetic for chronic pain, according to preclinical studies. The non-opioid approach could provide notable relief for millions who struggle to find adequate pain management.
arin Bhattacharjee, professor of pharmacology and toxicology at the University at buffalo’s Jacobs School of Medicine and Biomedical Sciences, described the molecule as acting like a local anesthetic, but with greater precision. Bhattacharjee is also cofounder of Channavix Therapeutics LLC, a startup aiming to commercialize these new pain relievers.
Unlike customary local anesthetics that block all sensation and have short durations,this new molecule specifically targets pain fibers and provides relief for up to three weeks with a single injection. The research, funded by the National Institutes of Health’s HEAL Initiative, appears in the journal Pain.
The molecule hones in on the Magi-1 protein, a key player in pain transmission. Magi-1 interacts with NaV1.8, an ion channel responsible for transmitting pain signals. By targeting this interaction, the new molecule disrupts the pain pathway.
Bhattacharjee explained that the molecule, a lipidated peptide, acts as a “decoy,” preventing NaV1.8 channels from binding to Magi-1. This leads to the degradation of the NaV1.8 channels,effectively blocking pain signals. The lipid modification allows the peptide to anchor within the neuronal membrane, protecting it from degradation and prolonging its effects.
“When this decoy peptide is introduced into pain neurons, it outcompetes NaV1.8 channels binding to Magi-1,” Bhattacharjee said. “The ‘liberated’ NaV1.8 channels are now left exposed as they become targets for degrading enzymes.”
The team confirmed the molecule’s effectiveness in human pain neurons, a crucial step toward potential drug growth.
What’s next
The next step involves toxicity trials. Bhattacharjee anticipates minimal toxicity due to the localized injection method. The team is seeking partners to advance the peptide to clinical trials, offering a potential new avenue for chronic pain treatment and pain relief.
